Wow, the exact same is happening to me
I have a line and stacked column chart where the measure I use for my line is below:
Total Budget (Non-Zero) = IF ( [Total Budget] > 0, [Total Budget] )
The measures I use for my column values are pretty straight forward
I have a slicer visual using a table column that is related to my fact table where my measures are pulling their values
When all values are selected on the slicer, everything shows fine, but if I select individual values on slicer, nothing changes in the line and stacked column chart
When I toggle the show marker to off, and republish, everything works as expected, just the marker doesn't show in my visual
This has got to be one of the strangest things I have seen
Thank you to acbg for also seeing this, I thought I was going crazy, and amazing how you found what seems to be causing this
